N. W., in England, have invented certain 1 new and useful Improvements in` Apparatus 'u tween the molding thereo with a comparatively slow continuous or for Treating Dough Preparatory to Baking, of which the following is a specification.

This invention relates to apparatus for the treatment of dough preparatory to baliing, and relates to apparatus concerned 1n the operation of provin said dough beandits introduction into the oven. For the purpose of this invention I .may

I -use a molding apparatus of any desired or approvedconstruction and preferably ladjacent to the discharge end or portion thereof I provide one or a series of endless-belt. or other conveyers on which are placed the lmown setting trays or boards on which the molded m'asses of dough either in tins or .otherwise are placed in series or -rows according tothe capacity of said trays. The said Yconveyer carries the Ytrays or boards intermittent movement (during which time they are filled with loaves to be proved) toward the proving apparatus proper, and

whenv the end of the conveyer is reached suitable mechanism 1s brought. into operation whereby a rapid lateral movement say at right angles to that of the conveyer is imparted to each tray in succession whereby it is transferred into or onto said proving apparatus. The mechanism' for effecting this rapid lateral transfer vis so arranged that avcomplete tray with its contents is fed to the prove;` before the next one on the conveyer comes into position and this may be effected in various ways, for example by l interrupted gearing which produces one rapid lateral feed movement to one slow intermittent feed movement of the conveyer. The lateral movement may also take place during a certain extent of continuous feed of the conveyer, or again may be effected by means of a transverse, chain, belt or equivalent provided with abutments or pushing members which through approprlate gearing operated for example by or from the conveyer feed mechanism, acton the trays to force them laterally at the desired times.

In one form the proving device comprises a single pair of chains with pivoted attachthe chain in the various directions given to same and during its passage around vthe wheels or pulleys. These chains may pass up into a'trunk or casing disposed immediately below the .ceiling of the bakehouse or other chamber land then down again to' a point Where the trays are discharged-for conveyance to theoven, the chains then returning below the Hoor tothe starting point.

The trunk or casing can be provided with pipes for passage of a heating medium or free steam may be admit-ted to said trunk for the purpose of keeping the dough moist and at desired temperature during the proving process. l

In another form the proving device comprises a 'conveyer band (or equivalent) traveling horizontally through a proving trunk, with an elevating and lowering device at each end, for raising or` lowering thetrays of dough to or from the trunk from the tray conveyer. deliver directly into the path of the elevator.

-the elevator taking the place of the lateral transfer for this purpose and being actu ated in the same manner as described for the lateral movement. Or a vertical trunk may be used in which the trays pass-either up or down or both up and down in being proved. I do not limit myself to the particular arrangement, position 0r course which same is caused to travel since these features may be determined by the particu- .lar exigencies of the buiiding or plant in question or other controlling circumstances. The proving trunks or devices may be made to operate in series.

. In this form the conveyer may Again instead ofthe single tins above referred to I may .use grouped or interconnected tins which are dealt with in the man1 ner above explained, and with their contents are fed into the oven. In this case the setting boards may be dispensed with, said groups of tins being directly handled by the conveye'r and prover and furthr the molded loaves, or tins containing same, or interconected groups of tins referred to may pass from one prover to another or others in series arranged in continuation of each other or relatively super-posed and from the last prover be fed onto a transverse or cross transfer conveyer moving say at right anvlews of machmmm mam-ed "me constmlcmn shown m mid. Figa ii-i. am@ lim. 'Referring to ifi 53. to l designates tbs hina may muwn or appr@ prima coustmcmn. mgmmm. sami, .mamme rmiss m. dough im ne moved Ummm m1 65' mm3 wwwa.

driving the various chains and conveyers that shown in the drawings comprising a pulley shaft 4.4 driving through gearing 45 a shaft 46 the latter driving interrupted gearing 47 for operating the cross transfer' chains 38 and bevel ear 48 on said shaft 45 driving the lifting chains 36. Shaft 46 also drives through beltor chain 49 gearing 50 which drives the conveyer chains 35 below the. fioor'and at the opposite end of the apparatus said chains drive through shaft 51 bevel gear 52 and spur gear 53 the .lowering` chains 34 the two pairs thereof being coupled by chain 54 and gears 55. r1`he pairs of lifting chains maybe similarly coupled. 3 l

In the construction shown in Figs. l1 to 13 the proving means proper is of a substantially known type comprising chains 60 carrying pivoted shelves or supports 61 for reception of the trays or boards or `the grouped and integral series of tins before referred to. Said chains pass alternately upward and downward about pulleys G2 and according to this form of the present invention are passed under the floor of the bakehouse or other chamber, as shown, extending at one side or end of the apparatus past a novel form of feed device 63 andat the other side or end past a novel form of delivery or discharge deviceffi which latter may convey the trays or groups of tins directly to the oven 65.

The feed device more particularly shown in-Fig. 12 and which may be used for either trays er grouped tins but shown as acting in conjunction withfthe latter comprises a slide or pushing member (3G adapted to be given rectilinear hori'ylontal movement at the required times by means of the levers' (37, rod (i8 and.'interrupted gearing 69- whereby the grpups ofins 70 is pushed off the conveyer 71 directly onto the shelves o1'. supports 61 of the proving chains 60. The gearing 6) is driven for example from the shaft 72 which drives said chains 60 by means of chain and chain wheels 73, shaft 74 and bevel gearing 75.

Where lgrouped tins only are being dealt' with a. ,similar mechanism to that just (lescribcd may be'used to deliver same from the chains G0 to thc oven 65 which in the form shown comprises atraveling endless belt 77. lVhere however trays or boards 78 with the tins thereon are used it is necessary to use the device more particularly shown in Fig. 1?. ln this construction the slide 7i) is operated-in a Similar manner tovslide' 66 desrribwl with rcl'crcnce to Fig. 12 but carries the tray 78 on a, forward extension 80,

lugs 81 holding the tray in piace. Above the slide is a finger or plate 82- mounted on a lever 82% the movenuants ol' which are controlled by a camtl operated from the interrupted gearing Gt) by means of a chain 85.

I 'do not limit myself to the particular ar I rangement and construction of. parts of the various embodnnents lof the invention hereinbefore described sincev the same maybe varied within limits determined by the following claims without departing from the spirit of the invention, but'l NVhat I claim as my invention and desire to secure by Letters Patent of the United States is -1.
